Halo will be reaching its 25th anniversary in 2026, which calls for its celebratory Halofest in December 2026. The special occasion will welcome Halo fans together during two events: the concert and the convention.
The first-ever Halofest concert will take place in Benaroya Hall in Seattle on December 11, 2026. It’s the first concert featuring the Halo franchise with music performed by the Seattle Symphony. The traditional Halo convention will continue the franchise’s celebration at the Seattle Convention Center on December 12, 2026 and December 13, 2026. The final two days of Halofest will allow anyone to invest in the Halo community by seeing Halo voice actors, participating in cosplay contests, meeting at the Community Stage, and several other activities.
Halo Fest tickets will go on sale on December 10, 2025, on a first-come, first-served basis. More about the types of tickets and offers will be detailed in November 2025.
